Abstract
The present invention relates to cleaning compositions comprising subtilisin proteases from Bacillus lentus having the following alterations: N76D, S103A and V104I, where the numbering is based on the corresponding positions in the subtilisin from Bacillus amyloliquefaciens.
Claims7
A fabric cleaning composition comprising:
- (a) from about 0.0001% to about 10% protease enzyme which is an N76D/S103A/V104I subtilisin variant derived from Bacillus lentus subtilisin;
- (b) at least about 5% surfactant;
- (c) at least about 5% builder;
- and
- (d) optionally, one or more cleaning composition materials compatible with the protease enzyme selected from the group consisting of solvents, buffers, enzymes, soil release agents, day soil removal agents, dispersing agents, brighteners, suds suppressors, fabric softeners, suds boosters, enzyme stabilizers, bleaching agents, dyes, and perfumes.
A dishwashing composition comprising:
- (a) from about 0.0001% to about 10% protease enzyme which is an N76D/S103A/V104I subtilisin variant derived from Bacillus lentus subtilisin;
- (b) from about 0.1% to about 10% surfactant;
- and
- (c) optionally, one or more cleaning composition materials compatible with the protease enzyme selected from the group consisting of solvents, buffers, enzymes, dispersing agents, suds suppressors, enzyme stabilizers, bleaching agents, dyes, and perfumes.
A method for cleaning fabric, said method comprising contacting a fabric in need of cleaning with a protease enzyme which is an N76D/S103A/V104I subtilisin variant derived from Bacillus lentus subtilisin.
A method for cleaning dishes, said method comprising contacting a dish in need of cleaning with a protease enzyme which is an N76D/S103A/V104I subtilisin variant derived from Bacillus lentus subtilisin.
